AHSB is our main project of the association and a continuation of our successful multi-year project. Adria Hydrofoil with which we competed in the international competition of radio-controlled boats Hydrocontest and today we are participating in the prestigious Monaco Energy Boat Challenge. The competition is held in the Principality of Monaco under the auspices of Prince Albert II and numerous sponsors.
The competition brings together experts in the field of technical sciences who design and build vessels of the future powered by renewable sources according to technical rules.
It encourages development and innovation in nautical and maritime technology and emphasizes the importance of preserving the environment. The competition takes place in three classes Energy, Solar and Open and is open to anyone who wants to contribute to the development of energy sustainable vessels.
The competition has been held since 2014 with students and engineers from various universities around the world, as well as associations and private companies.
Our first prototype boat for the competition was named Delta One because the boat was created as part of the Rowing club Jadran Rijeka located at Delta 1.
The vessel began to be designed and operated in 2020 and was successfully completed at the end of June 2021. The following are the main specifications and characteristics of the vessel.
The vessel and deck are made in a "sandwich" construction of styrofoam and PET core, carbon and glass fibers and epoxy resin using the Vacuum bagging technique.
Solar boat "Delta One" - The complete design, as well as the construction of the boat itself, was done entirely by the members.

E- Propulsion 6 kW outboard motor - Management of cable system and steering wheel
Bluetooth monitoring of consumption and state of energy obtained from solar panels
Battery pack 1.5 kWh (LiFePo4 cells) 14S13P battery pack - 48 V with air cooling
Connected to the battery via 2x MMPT in 6S and 9S mono crystal panels – Total installed power of solar cells 1050 W
Maximum speed of 14.7 knots
25 min at full speed, cruising speed 6 knots with an average consumption of about 1000 W
The goal of the project was to sail around the island of Krk (120 miles). The start of the project was November 2020, and the idea and the project of the solar vessel are being worked out for two years. First stage 30.10.2020 - Rijeka - Glavotok Krk (22 km) Second stage 31.10.2020 - Glavotok - City of Krk (18 km) Third stage 01.11.2020 - City of Krk - Baška (26km) Fourth stage 02.11.2020 - Baška - Vrbnik (22km) Fifth stage 03.11.2020 - Vrbnik - Jadranovo (20 km) Sixth stage 04.11.2020 - Jadranovo - Rijeka (15km)
